Abstract (en)
[origin: US2020188977A1] An efficient method for producing spring strut forks for motor vehicles is presented. In each case two spring strut forks are produced from a metallic extruded profile as a starting product. The extruded profile has a central, middle main chamber and four longitudinal chambers which are arranged offset with respect to one another over the circumference of the main chamber. Wall portions of the main chamber which are situated between the longitudinal chambers are removed, and the extruded profile is severed into two semifinished parts. Each semifinished part has one cylinder portion and two oppositely situated arm portions which project relative to the cylinder portions. The semifinished parts are subsequently mechanically machined, and one spring strut fork is produced from each semifinished part.
